MAGAZINE PENCIL. f i Q Application filed March 26. 1923. Serial No, 627,555.

To all whom it may concern: 1

Be it known that l. GERALD L. .BASSIJTT, a citizen of the United States, and a resident of Toledo, in the county ofLucas and tive to other parts of the pencil, and pref erably in a manner to facilitate separation for substitution or repair.

The object of the invention is the provision. of simple, efficient and economical means for frictionally retaining the fluted tube member and barrel in assembled relation and permitting an easy separation thereof when desired.

The invention isfully described in the following specification, and While in its broader aspect it 'is capable of different forms, a preferred embodiment thereof is illustrated in the accompanying drawing, in Which,-

Fig. 1 is a side elevation of a portion of a pencil embodying the invention, with parts broken away. Fig. 2 is an enlarged cross-section on the line 22 in Fig. 1. Fig. 3 is an enlarged longitudinal section of the portion of the pencil embodying the securing means. Fig. 1 is a plan view of the securing spring, and Figs. 5 and 6 are sections taken on the lines and 66 respectively, in Fig. i. 7

Referring to the drawings, 1 designates the outer longitudinally slotted tube member of the lead actuating mechanism of the pencil, and 2 the pencil barrel which telescopes over the tube and is centrallv spaced therefrom by longitudinally extending ribs or flutes 3 on the tube to form a plurality oflead storing pockets 4. between the tube and barrel. The tube and barrel are intended to be fixedly connected to turn together relative to a member 5, in the present instance, forming the tip of the pencil, which member is connected to another part of the leadactuating mechanism, as well understood in the art, whereby a relative turningof-said memberfiand barrel effects anfactuation of the lead rib 3 for engagement with the barrel Wall to firmly retain the barrel and tube in assembled relation.

form of thin spring metal and has each end 3 j The invent-ion consists in providing. the outer edge of one of the ribsorflutesB or the tubel with a prolonged incutg'ornotch 6 in which a spring member 7 is '.disp'o'sed,

provided with a notch 8 for straddling the base and end walls of the notch 6 when seated in the notch, as illustrated. The spring is bowed to an extent suflicient to place its central portion without the notch 6 when the spring is seated in such notch,

so that the barrel 2 in being forced over the flutes 3 of the tube 1 passes over and causes a compression or inward springing of the outwardly bowed engaged portion of'the spring member, as shown in Figs 1 and It is evident that the-spring exerts considerable frictional resistance on the barrel to prevent its withdrawal from the tube and also quite effectually locks the barrel and tube together to cause themto turn in unison. This locking action isfacilitated by burring or so stamping the spring members that a slight outwardly turned edge burr or flange 9 is formed on the side edges of the spring for cutting into the barrel wall as it is forced thereover, as illustrated in a somewhat exaggerated manner, in Fig. 2. lVith this arrangement it is evident that the. spring member is locked against turning relative to the tube by reason of the notched engagen'ient of the spring ends to the rib and that the barrel-and edge portions of the spring are interengaged to prevent relative turning movements thereof. The spring member 7 is normally flat in crosssection and is given a slight transverse bow by the engagement of the barrel therewith.

It is found in practice that this means of securing the barrel and fluted tube member together is veryeflicient and enables a rapid and easy assembling of the .parts and also 65' The spring member 7 is made in elongated stitution or inspection of the lead actuating mechanism.

I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of embodiment, in numerous forms without departing from the spirit of the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is, i j

1. In a pencil of the class --described, a longitudinally fluted tube, aba'rrel mounted over the tube, said tube havinga notch in the outer edge of one of its flutes, and a bowed spring member mounted in the notch I and having" its ends notched to straddle poring with the barrel wall to firmly connect the barrel and tube to resist relative rotary and longitudinal movements thereof.

2; In a pencilof the class described, a longitudinally fluted tube having a notch in 2 -gaging the barrel Wall to resist relative rotary and longitudinalmovements ofthe barrel and tube, theside edges of the spring member being bowed'to cut into the barrel wall when thebarrel is forced longitudinally over the tube. n

In testimony whereof I have hereunto subscribed my name to this specification. v
